Application filed April 24, 1914. Serial No. 834,261.

T 0 all whom it may concern Be it known that I, MASON I. CHAPIN, acitizen of the United States, residing at Greeley, in the county of Weldand State of Colorado, have invented certain new and useful Improvementsin Head-Gates for Ir rigation-Ditches, of which the following is aspecification.

This invention relates to head-gates for irrigation ditches and has forits object the provision of a simple and etlicient apparatus, by the useof which a constant flow of water in the lateral will be permittednotwithstanding variations in the head of Water in the main ditch.

Secondary objects of the invention are to provide means whereby the flowof water may be entirely out off if desired, and also to provide meanswhereby the quantity of water flowing to the lateral may be regulated.

These stated objects, and such incidental objects as will appear as thedescription of the device proceeds, are attained in a mechanism of thetype illustrated in the accompanying drawings, and the invention residesin certain novel features which will be hereinafter first fullydescribed and then more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an elevation of my improvedhead-gate looking at the same from the main ditch and showing the floatand the casing in vertical section; Fig. 2 is a plan view; Fig. 3 is anelevation looking at the device from the lateral ditch; Fig. 4 is anenlarged detail sectional view.

In carrying out my present invention, I preferably provide a casing orhousing 1 at the junction of the main ditch 2 and the lateral-ditch 3,which may be of any preferred or convenient construction and is providedwith a suitably grated inlet opening to permit the flow from the mainditch, and at the opposite side with a suitable outlet to permit theflow into the lateral ditch.

A partition 4 is provided in the housing or casing which extendstransversely with respect to the lateral ditch, and this partition isprovided with a suitable opening in its lower portion, while around thesaidopening a collar or annular flange 5 is rigid with the partition,said flange or collar being internally threaded, asshown at 6. A shortpipe or conduit 7 is extended through the said opening and collar, andupon the said pipe is brazed or otherwise rigidly se cured a collar orring 8 which is externally threaded so as to fit Within the collar orflange 5 and form a water-tight joint therewith to permit the tube orconduit 7 to rotate therein. At that side of the partition 4: which isnearer the outlet, the end of the tube or conduit 7 is provided with arigid flange 9, to which is secured a flange 10 on one end of a pipe 11which extends toward the outlet and is disposed parallel with thepartition, a gasket 12 being fitted between the flanges 9 and 10 so asto provide a watertight joint and prevent leakage. The free end of thepipe 11 is provided with an outlet opening indicated at 13, and thisopening is preferably formed in the side of the pipe facing the outletso that the water passing therethrough will be directed toward theoutlet, as will be readily understood. Upon the pipe immediately overthe said opening 13 is provided a short standard or bracket 14 carryinga guide 15 in which is mounted a slidable stem or operating rod 16. Tothe lower end of the stem or rod 16 are pivotally attached the upperends of divergent links 17 which have their lower ends pivotally attached to sliding cutoffs 18 which are mounted in guides 19 provided onthe pipe 11, so that the quantity of water escaping from the pipe may beregulated according to the desires of the user. The bracket 14 isdisposed over the center of the opening 13 so that the cut-ofis orslides will cover or uncover equal portions of the opening for a purposewhich will presently appear. It

will be understood, of course, that if the slides be brought togetherthe opening will he completely covered and the flow of water from thepipe entirely cut oil. To that end of the tube or pipe 7 which is nearerthe inlet, I rigidly secure a lever 20 which extends laterally from thesaid pipe parallel with the partition 4 and the pipe 11 and has its freeend directly in line with the center of the opening 13. A float 21 iscarried by the free end of the lever, and the said float is looselyconnected with the lever so that it may be adjusted as may be desired todetermine the head of water which will be available to the user.

As clearly shown in Figs. 1 and 2, the float is constructed with a slotor notch 22 which receives the end of the lever 20, and is also providedwith a keeper or hearing bracket 23, through which passes a bolt orthreaded post 2% which projects above the float and has it lowerendloosely fitted to the end of the lever. The post is provided with aflat face 25 upon one side, upon which may be marked a scale ofgraduations, and a winged nut 26 is fitted upon the post above the floatso as to be turned home against the top of the float and therebyregulate the head of water. lithe winged nut be set at a point nearerthe upper end of the post, the float Will, of course, be spaced somewhatfrom the end of the lever, and as the end of the lever is directlyalined with the center of the opening 13 it will be seen that byadjusting the float the said opening will be maintained constantly atany desired distance below the level of the water.

Should it be desired for any reason to cut ofl the flow entirely andrender. the device inoperative, the entire apparatus may be held in anelevated position, as indicated in dotted lines in Fig. 3, by engaging achain or similar flexible connection 27 which is secured to the pipe 11over a'hook or other holding device 28 provided upon the upper edge ofthe partition. 1 i

It is thought the operation of my improved device will be readilyunderstood from the foregoing description taken in connection with the"accompanying drawings. The water flowing through the inlet opening intothe casing will rise between the inlet side of the casing and thepartition 4, and as the float 21 will remain upon the surface of thewater, the lever 20 will, of course, swing upwardly as the level of thewater rises. Inasmuch as the lever 20, the tube 7 and the pipe 11 arerigidly connected, the tube 7 will turn in its bearing in the partition1 and the pipe 11 will, of course, swing upwardly to the same extentthat the lever 20 swings upwardly. Consequently, the outlet opening 13will remain constantly at a fixed distance below the surface of thewater, and the head of water flowing into the lateral ditch will notvary. If the winged nut 26 be adjusted to the'upper extremity of thestud 24, the float will be set at its maximum distance from the end ofthe. lever 20 and, consequently, there will be a greater distancebetween the surface of the water and the end of the lever. Inasmuch asthe center of the opening 13 is in the same horizontal plane as the endof the lever, the head or pressure of water flowing through saidopeningmay be accurately regulated. As the level of the water in themain ditch falls the lever 20 will, of course, swing downwardly inasmuchas the water in front of the partition 4 is always at the same. level asthewater in the main ditch, and it will, therefore, be readily seen thatvariations in the levelof the water in the main ditch will not affectthe-pressure in the lateral ditch which will always be the same.

My present device is exceedingly simple prising a partition disposedtransversely of the lateral ditch, a pipe rotatably mounted in saidpartition and extending therethrough, an outlet pipe extending from thesaid rotatable pipe and provided with an outlet opening at its free end,a lever rigid with the rotatable pipe and extending therefrom parallelwith the outlet pipe and having its free end horizontally alined withthe center of the said outlet opening, and a float carried by the freeend of the lever.
